Well i can understand his point, he wants to have a lot of action just incase you got through prolonged periods of someone not attacking you. But as Jason has stated, if NPC's were to make sieges as well, it would be to easy for a human player to come at the same time or straight after knowing your army would be stretched.

i have seen a lot of info on players attacking your homeland. i think there should be npc's that seige your homeland or atleat raid your mines, farms and setup camps for you to destroy.

Some semblance of NPC raids and what not is likely implemented in-game just because of the strategic value to doing so - but I refer you to one glaring example of this going horribly wrong in an RTS game: Battle for Middle Earth 2. The AI in that game would, for the most part, ignore your armies and just waltz over to your farms/mines/lumber mills, destroy them, and move on to the next one. This made the AI maddeningly frustrating to play against since you knew going into it that enemy armies wouldn't battle you - they'd just raid you like there was no tomorrow.

Maddenning, MADDENNING I tell you!

So to the DoF devs... please... don't let NPC players go overboard with that raiding business. It might work in war - but hey, gaming first here.

They have mentioned dwarven lands, etc. being explorable and I would assume that there are npc settlements there that we can attack. Aside from that..

I would say that this could be implemented in two ways.:

1. Roving NPC warbands. They could have roving NPC warbands that function kindof like rebel armies in Rome: total war. They generally do not attack your strongholds (because they aren't often strong enough). However, their presence near your stronghold weakens you. It reduces your production. Therefore, you have to leave your stronghold to go kill them. These wouldn't be a constant threat, more of an occasional nuisance to throw some variety into the game.

2. Very rare npc attacks. NPC armies that raid your stronghold very rarely, more of an event than an occasional happening. Perhaps a powerful force that appears and attacks several strongholds before either being destroyed or leaving for another area.
